Abstract (en)
An estimation device for estimating a conversion factor which is a ratio between the number of photoelectrons generated from a pixel in response to inputting of light to the pixel and an electrical signal intensity output in response to the number of photoelectrons is provided. The estimation device includes: an acquisition unit configured to acquire a plurality of data groups including the electrical signal intensity for each of a plurality of pixels when light is input to the plurality of pixels; and a calculation unit configured to calculate the conversion factor for each of the plurality of pixels from the plurality of data groups based on a likelihood function indicating a likelihood of the conversion factor corresponding to the output electrical signal intensity.
